Device designed to keep the cells of a Humanoid body entertained and so keep them for dying off during the ageing process. Spending a sizeable fraction of each day in the machine would, possibly, result in immortality. The device used highly charged polaric particles.13

A system developed by the Romulan Empire to render its vessels virtually undetectable to an enemy. Cloaking devices have varied greatly in effectiveness as cloaking and sensor technology have competed with one another. In general, it is impossible for a ship to fire a weapon whilst cloaked.36As of the TNG era, a tachyon network was considered to be the most effective method of detecting cloaked vessels.37

A method of creating a new body by duplicating the DNA of an existing cell. A clone is effectively the identical twin of the person it was cloned from. In 2365 the Enterprise-D encountered an entire society composed of clones of five people.38 In 2369 a group of Klingons created a clone of the revered leader Kahless the Unforgettable in an attempt to depose Gowron.39 During the same year a criminal called Ibudan created and murdered a clone of himself in an attempt to frame Constable Odo.40 At some point the Romulans created a clone of Captain Picard, planning to train him to replace the Captain as a Romulan agent at some future time. The plan was later abandoned.41

A measure of subspace field stress. A field of greater than 1 Cochrane is a warp field, allowing velocities greater than light to be attained. For a vessel in such flight, the Cochrane value of its warp field is equal to the velocity in multiples of the velocity of light. The unit was named after Zefram Cochrane, the inventor of Warp Drive.45

Any device which allows communication across large distances. As of the 24th century, personal communicators were contained within the Starfleet emblem worn on the uniform. This device was able to operate over ranges of at least several dozen light seconds.33

Imaginary substence created by Kirk as a bluff against a vessel of the First Federation. Corbomite was claimed to be able to redirect any attack back upon the attacker, rendering Federation Starships invulnerable. The ploy worked.60

Extremely thin filament composed of almost infinitely dense matter. Although such strings are no wider than a proton, they have a powerful gravitational field. They also emit a set of subspace frequencies.56

A device capable of suspending life in an organic body for long periods by placing it into a suspended animation state involving very low temperatures. The Retellians used cryopods to transport living beings as cargo in the 2150s.30
